Prosocial behavior from early to middle childhood: Genetic and environmental influences on stability and change.

Prosocial behavior is important for the functioning of society. This study investigates the extent to which environment shared by family members, nonshared environment, and genetics account for children's prosocial behavior. The prosocial behavior of twins (9,424 pairs) was rated by their parents at the ages of 2, 3, 4, and 7 and by their teachers at age 7. For parent ratings, shared environmental effects decreased from .47 on average at age 2 to .03 at age 7, and genetic effects increased from .32 on average to .61. The finding of weak shared environmental effects and large heritability at age 7 was largely confirmed through the use of teacher ratings. Using longitudinal genetic analyses, the authors conclude that genetic effects account for both change and continuity in prosocial behavior and nonshared environment contributes mainly to change.

Aggressive behavior in childhood and early adolescence: an ecological-developmental perspective on youth violence

This article reviews recent research on the development of aggressive behavior in childhood and early adolescence using an ecological perspective that focuses on social development in the family, school, peer group, and community. Special emphasis is placed on family processes and early childhood peer relations that appear to tip developmental trajectories toward social rejection at school and use of aggression to achieve social goals in interpersonal relationships. The article discusses implications for preventing youth violence.     

Conflict and friendship relations in middle childhood: behavior in a closed-field situation

Disagreements between school-aged children were examined as a function of friendship status. 66 same-sex dyads were selected, including equal numbers of "best friends" and nonfriends, who were then observed while playing a board game (a closed-field situation). Conflicts occurred more frequently among friends than among nonfriends and lasted longer. Friends did not talk more during their conflicts than nonfriends, but assertions were used selectively according to friendship and sex: With friends, girls used assertions accompanied by rationales more frequently than boys whereas boys used assertions without rationales more frequently than girls. These sex differences were not evident during conflicts between nonfriends. Results are discussed in relation to the social constraints intrinsic to closed-field competitive conditions as they apply to friendship relations in middle childhood.     

Clinically significant behavior problems during the initial 18 months following early childhood traumatic brain injury.

Objective: This study looked at the emergence of clinically significant problems in behavior, executive function skills, and social competence during the initial 18 months following traumatic brain injury (TBI) in young children relative to a cohort of children with orthopedic injuries (OI) and the environmental factors that predict difficulties postinjury. Participants: Children, ages 3–7 years, hospitalized for severe TBI, moderate TBI, or OI were seen shortly after their injury (M = 40 days) and again 6 months, 12 months, and 18 months postinjury. Design: Behavioral parent self-reports, demographic data, family functioning reports, and home environment reports were collected at injury baseline and each time point postinjury. Results: Results suggest that, compared with the OI group, the severe TBI group developed significantly more externalizing behavior problems and executive function problems following injury that persisted through the 18-month follow-up. Minimal social competence difficulties appeared at the 18-month follow-up, suggesting a possible pattern of emerging deficits rather than a recovery over time. Conclusions: Predictors of the emergence of clinically significant problems included permissive parenting, family dysfunction, and low socioeconomic status. The findings are similar to those found in school-age children. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Dimensionality of an early childhood scale using rasch analysis and confirmatory factor analysis

This paper explores the use of Rasch analysis and linear confirmatory factor analysis as methods for investigating the dimensionality of an early childhood test (Gesell School Readiness Screening Test), taking into account the theoretical basis of test construction. The paper presents the results of empirical analyses using both approaches and discusses the theoretical and psychometric considerations that guide the selection and application of each technique.     

Sibling relationships in early/middle childhood: links with individual adjustment.

The overarching goal of the study was to identify links between sibling relationship quality in early/middle childhood with children's adjustment, having accounted for the effects of parent-child relationship quality. The sample consisted of 101 working and middle-class 2-parent English families with 2 children ages 4-8 years. Parents provided reports of sibling relationship quality, the parent-child relationship, and the children's prosocial and problematic behaviors. The children also provided reports of their familial relationships with a puppet interview. Results indicated that sibling relationship quality was associated with the older siblings' adjustment, controlling for the children's relationships with parents. In addition, the pattern of findings suggested that positivity within the sibling relationship was more strongly linked with child adjustment than was sibling conflict.

Father absence during early childhood and anti-social behavior.

Parson's suggestion that difficulties in achieving adequate sex-role identification is a significant source of male antisocial behavior, leads to the hypothesis that father absence during early childhood will be related to antisocial acting out. A comparison of the responses of 51 "father-absent" male medical students to an anonymously administered antisocial behavior scale with those of 89 comparable "father-present" students supports the hypothesis.

Relation of early socialization experiences to aggression in middle childhood.

A follow-up study (7 years after) on the Ss in the original investigation on patterns of child rearing (Sears et al., 1957). Parental attitude towards child rearing and attitudes towards aggression when S was 5 were related to patterns of aggressive behavior and attitudes toward agression expressed by Ss at age 12. The manner of expressing aggression was seen to be a function of sex of the child and specific familial attitudes. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Stability and change in aggression and withdrawal in middle childhood and early adolescence.

Examined stability and change in aggression and withdrawal in the context of both normal and deviant behavioral development. The design included 3 age cohorts with a total of 653 Ss separated in age by 3 yrs. Aggression and withdrawal were measured using the Peer Evaluation Inventory initially when the Ss were in Grades 1, 4, and 7 and a 2nd time when the Ss were in Grades 4, 7, and 10, respectively. Members of 4 classification groups were included in the sample: 183 Ss in an aggressive group, 219 Ss in a withdrawn group, 251 Ss in an aggressive-withdrawn group, and a nondeviant control group consisting of 1,103 Ss. The stability of aggression was found to be moderately high, regardless of sex of S or grade at time of initial assessment. Moderate stability was found for withdrawal for both boys and girls when initial assessments were conducted at Grades 4 and 7. The withdrawn Ss became more withdrawn over the 3-yr period. It is concluded that, for many children, the problems of aggression and withdrawal do not appear to be transitory. (34 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Sibling influences on gender development in middle childhood and early adolescence: A longitudinal study.

The development of gender role qualities (attitudes, personality, leisure activities) from middle childhood to early adolescence was studied to determine whether siblings' gender role qualities predicted those of their sisters and brothers. Participants were 198 firstborn and second-born siblings (Ms?=?10 years 9 months and 8 years 3 months, respectively, in Year 1) and their parents. Families were interviewed annually for 3 years. Firstborn siblings' qualities in Year 1 predicted second-born children's qualities in Year 3 when both parent and child qualities in Year 1 were controlled, a pattern consistent with a social learning model of sibling influence. Parental influence was more evident and sibling influence less evident in predicting firstborns' qualities; for firstborns, sibling influences suggested a de-identification process.

Temperament profiles from infancy to middle childhood: Development and associations with behavior problems.

The authors applied I-States as Objects Analysis (ISOA), a recently proposed person-oriented analytic approach, to the study of temperament development in 921 Norwegian children from a population-based sample. A 5-profile classification based on cluster analysis of standardized mother reports of activity, sociability, emotionality, and shyness at ages 18 months, 30 months, 4-5 years, and 8-9 years was interpretable and highly replicable. The prevalence of temperament profiles changed markedly with age, and individual stability in temperament profiles was significant. Specific typical and atypical developmental sequences of profiles were identified. Selective patterns of concurrent group differences in externalizing and internalizing problems by temperament profiles were remarkably similar across ages. The findings to some degree support the notion that individual temperament-variable values take on meaning in relation to the whole individual configuration and indicate some lawfulness in temperament changes over time. Future person-oriented studies of temperament development should replicate the current results using multiple data sources, rigorous tests of gender differences, and latent group modeling.

Parental corporal punishment predicts behavior problems in early childhood.

Using data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (Research Triangle Institute, 2002), this study examined the impact of corporal punishment (CP) on children's behavior problems. Longitudinal analyses were specified that controlled for covarying contextual and parenting variables and that partialed child effects. The results indicate that parental CP uniquely contributes to negative behavioral adjustment in children at both 36 months and at 1st grade, with the effects at the earlier age more pronounced in children with difficult temperaments. Parents and mental health professionals who work to modify children's negative behavior should be aware of the unique impact that CP likely plays in triggering and maintaining children's behavior problems. Broad-based family policies that reduce the use of this parenting behavior would potentially increase children's mental health and decrease the incidence of children's behavior problems.

Relation between mastery behavior in infancy and competence in early childhood.

[Correction Notice: An erratum for this article was reported in Vol 22(6) of Developmental Psychology (see record 2008-10958-001). In the article, an incorrect copyright note has been given. The copyright note has been corrected and is included in the erratum.] 53 infants were observed at 6 and 12 mo of age during 2 24-min play sessions. The Bayley Scales of Infant Development (BSID) were given at 6 and 12 mo and the McCarthy Scales of Children's Abilities (MSCA) at 30 mo of age. Results reveal that measures of competence in infancy (successful task completion during play and the BSID scores) were not strongly correlated with the 30-mo MSCA scores. In contrast, infant mastery behavior during play strongly predicted MSCA scores: The time spent investigating toys at 6 mo and persistence in solving tasks at 12 mo of age were behaviors significantly positively correlated with the MSCA scales. It is suggested that infant behaviors that predict later competence do not remain static but change with age and that infants' mastery behavior is a more effective predictor of later development than their competence with either toys or developmental tests.

Heterogeneity among peer-rejected boys across middle childhood: Developmental pathways of social behavior.

The purpose of this longitudinal study was to identify subgroups of rejected boys with different developmental pathways of aggression and prosocial behavior across the elementary school years. Peer, teacher, and parent reports and behavior observations yielded composite scores for aggression and prosocial behavior at 3 measurement waves. A cluster analysis with these composites on 87 initially rejected boys identified 4 subgroups with different developmental pathways of prosocial behavior and aggression that were associated with different patterns of sociometric acceptance and rejection over time and with social emotional adjustment in the last measurement wave. Changes in acceptance and rejection tend to precede changes in aggression and prosocial behavior. Cluster differences on social emotional adjustment indicators converged into 1 moderately discriminating factor, Social Maladaptation in Peer-Oriented Behavior.

Pathways from childhood abuse and neglect to HIV-risk sexual behavior in middle adulthood.

Objective: This study examines the relationship between childhood abuse and neglect and sexual risk behavior in middle adulthood and whether psychosocial factors (risky romantic relationships, affective symptoms, drug and alcohol use, and delinquent and criminal behavior) mediate this relationship. Method: Children with documented cases of physical abuse, sexual abuse, and neglect (ages 0–11) processed during 1967–1971 were matched with nonmaltreated children and followed into middle adulthood (approximate age 41). Mediators were assessed in young adulthood (approximate age 29) through in-person interviews between 1989 and 1995 and official arrest records through 1994 (N = 1,196). Past year HIV-risk sexual behavior was assessed via self-reports during 2003–2004 (N = 800). Logistic regression was used to examine differences in sexual risk behavior between the abuse and neglect and control groups, and latent variable structural equation modeling was used to test mediator models. Results: Child abuse and neglect was associated with increased likelihood of risky sexual behavior in middle adulthood, odds ratio = 2.84, 95% CI [1.74, 4.64], p ≤ .001, and this relationship was mediated by risky romantic relationships in young adulthood. Conclusions: Results of this study draw attention to the potential long-term consequences of child abuse and neglect for physical health, in particular sexual risk, and point to romantic relationships as an important focus of intervention and prevention efforts.

The mediation of reward-induced motivation decrements in early and middle childhood: A template matching approach.

Under certain circumstances, children's intrinsic motivation (IM) to engage in an activity may be undermined as a consequence of being induced to engage in that activity in return for tangible rewards. The present study with 25 females and 20 males (4–10 yrs) attempted to identify the process(es) mediating this effect during early and middle childhood, by simultaneously testing 5 hypotheses that may plausibly be advanced to account for it. The possibility that different mediators may be operative at different age levels was also examined. IM was assessed before and after an offer and delivery of reward contingent on task engagement. Independently, predictions (templates) were derived from each hypothesis regarding the personality characteristics of an S predicted to exhibit the greatest reward-induced decrement IM. Individual differences in Ss' personalities were assessed on the California Child Q-Sorts, which were then matched with each template to predict motivation decrement. Among males, 2 hypothesized mediators in which the perception of personal control is central accounted for significant portions of the variance in motivation decrement. None of the hypotheses were supported among females. Some developmental changes in mediation were also found and discussed. (32 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Children's attachment representations: Longitudinal relations to school behavior and academic competency in middle childhood and adolescence.

A longitudinal study examined children's (N?=?108) attachment representations in relation to behavior and academic competency at school during middle childhood and adolescence. Attachment representations were assessed from children's responses to a separation story at age 7 years. At ages 9, 12, and 15, teachers rated children on four dimensions of school behavior: attention–participation, extroversion, disruptive behavior, and insecurity about self. Children's grade point average (GPA) in school was also examined. Children's attachment representations (secure vs. insecure) did not predict either disruptive behavior or extroversion, but they were significantly linked to attention–participation, insecurity about self, and GPA, with secure representations being associated with more favorable outcomes. The study controlled for social class, gender, IQ, perspective-taking ability, and prior competency. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Environmental risk factors and children's achievement from middle childhood to early adolescence.

This study examined the long-term effects of low family income and stressful life events on math and reading achievement test percentile scores for 1,253 children. Four birth cohorts were followed for 2-4 years so that achievement across Grades 2 through 7 could be examined. Two types of analytic models, the multiplicative risk factor model and the cumulative risk model, were used. The moderating effects of ethnicity and gender were also explored. The results suggest that low income and minority ethnic status are significant risk factors for children's achievement. No systematic evidence was found for a large impact of life events on reading achievement, and the effects of such events on math achievement appear to be best understood as part of the larger context of multiple risk factors during childhood. The findings suggest a differential impact of risk factors on math achievement compared with reading achievement. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Developmental trajectories of anxiety symptoms among boys across early and middle childhood.

This study examined the developmental trajectory of anxiety symptoms among 290 boys and evaluated the association of trajectory groups with child and family risk factors and children's internalizing disorders. Anxiety symptoms were measured using maternal reports from the Child Behavior Checklist (T. M. Achenbach, 1991, 1992) for boys between the ages of 2 and 10. A group-based trajectory analysis revealed 4 distinct trajectories in the development of anxiety symptoms: low, low increasing, high declining, and high-increasing trajectories. Child shy temperament tended to differentiate between initial high and low groups, whereas maternal negative control and maternal depression were associated with increasing trajectories and elevated anxiety symptoms in middle childhood. Follow-up analyses to diagnoses of preadolescent depression and/or anxiety disorders revealed different patterns on the basis of trajectory group membership. The results are discussed in terms of the mechanisms of risk factors and implications for early identification and prevention. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Sibling relationships from the preschool period through middle childhood and early adolescence.

Studied the stability and correlates of individual differences in children's relationships with their siblings between early childhood and adolescence in 39 sibling dyads, using home observations and maternal interviews in the early childhood period and interviews with mothers and children at the later time points. Stability of individual differences found over 7 yrs increased with age. The behavior of the other sibling in the preschool period related to both older and younger siblings' behavior at the last time point. Life events were associated with increased warmth between the children. By preadolescence, gender and SES were related to differences in the relationship. Multiple regression showed that preschool measures of sibling interaction contributed independently of gender and SES to the variance in individual differences in positive aspects of the relationship at early adolescence.
